A slipper clutch, also known as a back-torque limiter or a clutch assist, is a specialized clutch mechanism designed for high-performance motorcycles and cars. It is designed to prevent excessive engine braking and rear-wheel locking, which can cause the rider to lose control of the vehicle during downshifts.
What is the purpose of a slipper clutch?
The main purpose of a slipper clutch is to reduce the risk of wheel hop, which can occur when a rider or driver abruptly downshifts at high speed. When a rider or driver downshifts, the engine braking can cause the rear wheel to lose traction and lock up, leading to a skid or loss of control. A slipper clutch allows the clutch to slip, preventing excessive engine braking and allowing the rear wheel to spin freely, reducing the risk of wheel hop.
How does a slipper clutch work?
A slipper clutch works by using a set of ramps and balls to disengage the clutch when the engine tries to lock up the rear wheel during a downshift. When the rider or driver downshifts, the engine braking causes the rear wheel to spin faster than the engine speed. The slipper clutch disengages the clutch when this happens, allowing the rear wheel to spin freely and preventing wheel hop.
Who invented slipper clutch?
The slipper clutch was first invented by a Japanese motorcycle racer named Hideo “Pops” Yoshimura in the 1980s. Yoshimura was looking for a way to reduce the risk of wheel hop during high-speed downshifts, and he developed the slipper clutch as a solution.
Are slipper clutches worth it?
Slipper clutches are generally considered to be worth the investment for riders and drivers who frequently engage in high-speed downshifting. They can help prevent wheel hop and improve overall control of the vehicle. However, slipper clutches can be expensive and may not be necessary for everyday use.
What is the advantage of slipper clutch?
The main advantage of a slipper clutch is that it can help prevent wheel hop and improve overall control of the vehicle during high-speed downshifting. Slipper clutches can also reduce wear and tear on the transmission and clutch components, leading to longer-lasting parts and potentially reducing maintenance costs over time.
